Reference Plane Elevation

611 Views, 4 Replies
04-25-2012 10:06 PM

When we draw a reference plane in a project in the Level 1 (0'  0" Elevation) then the  reference plane elevation shows  4’ 0” in the Specify Shared Coordinates Tab.  Why the elevation of reference plane shows the 4’ 0” height?  Is it default elevation for reference plane? See the attached jpg .Please help in this issue. Thanks in advance.

Reference planes do not have an elevation value. So, in this case, those values do not refer to the reference plane. Most likely, the project based point has been modified, "moving" the whole project 4 feet up. To correct it, select the project base point in a site plan view, and change its "z" value to 0.

Thanks for your clarification.

But we can't move the project based point. We have studied in this topic and finally come to the solutions that it's elevation shows because of View Range Setting (Level 1: Default Cut Plane 4' & Site :Default Cut Plane 200')

I have attached a jpg.

by default all plans' cut plane is set to 4'-0" or 1200mm in Revit Architecture.

Revit Structure has different settings (1'-0") as by default cut plane.

 

If you draw a wall (or other model elements), these will be drawn in reference to respective levels since their 'Base Constraint' is set as Level Name and Base Offset is 0'-0".

 

In case of rerence plane, these parameters (base constraint and base offset) are not available, so reference plane shared parameter properties shows the value as 4'-0" (cut plane).

  • Reference planes do not have an elevation value.
  • View range does not have anything to do with the elevation value of an object.
